Abstract:
The dataset contains anticipated desert bighorn sheep habitat on the Arizona Strip. Before 1988, Standard USGS topographical maps were used to identify elevations over 3,600 feet in mountain ranges that sheep were known to occupy. Then, areas where sheep were not found or reintroduced were eliminated.

The dataset contains anticipated desert bighorn sheep habitat on the Arizona Strip. Before 1988, Standard USGS topographical maps were used to identify elevations over 3,600 feet in mountain ranges that sheep were known to occupy. Then, areas where sheep were not found or reintroduced were eliminated.

Purpose:

For regional analysis and display at 1:24,000. This dataset was created for wildlife management purposes. This dataset was used in the ASDO resource management planning process.

Supplemental information:

Dataset locally known as bighorn. This dataset and other datasets in the Arizona Strip District Office Geographic Information Database (ASDOGID) represent data for the BLM Arizona Strip District Office, and may include the Arizona Strip Field Office, Vermilion Cliffs National Monument (VCNM) and/or the Grand Canyon-Parashant National Monument (GCPNM or PARA). The Grand Canyon-Parashant National Monument is managed jointly by the BLM and the National Park Service (NPS).
Desert bighorn habitat is typically rough, rocky and broken by canyons and washes. Many areas with rough elevation within the Arizona Strip provide the right habitat conditions for bighorn to survive. Bighorn habitat needs the right mix of food, water, space and escape cover, although the exact proportions in the mix are not completely agreed upon.

This data should not be used at a scale larger than 1:24,000. The data and corresponding attributes are only as accurate as the source maps from which they were obtained, and may vary depending on the data and method of acquisition.
This data is suitable for regional planning, management decision support at intermediate scales (i.e. 1:24,000 or smaller), and cartographic purposes. The data is not suitable for analysis at scales larger than 1:24,000.
If the Receiving Agency (RA) has modified the data in any way, they are obligated to describe the types of modifications they have performed on hardcopy maps utilizing the data. RA specifically agrees not to misrepresent ASDOGID datasets or to imply that any changes made were approved by BLM ASDO or NPS.
No warranty is made by the BLM/NPS for use of the data for purposes not intended by BLM/NPS. This information may be updated without notification.

Feature attributes were taken from source material. Code assignments are believed to be representative of the source document.

Logical consistency report:

Data was reviewed for correct topological structure. Duplicate lines have been removed.

Completeness report:

This dataset covers the entire BLM Arizona Strip District. It is constantly being reviewed and added to as additional information becomes available.

Positional accuracy:

Horizontal positional accuracy:

Horizontal positional accuracy report:

Overall horizontal accuracy for this data is not greater than national mapping accuracy standards (NMAS) for USGS source maps. Snapping and coordinate shift tolerances were maintained at 0.01 meters or less through editing. Horizontal positional accuracy for the digital data set was tested by visual comparison of the source data with hard copy verification plots.

Process description:

A meeting was held where standard USGS topographical maps were used by managers to identify elevations over 3,600 feet in mountain ranges that sheep were known to occupy. Habitat polygons were identified based on elevation, vegetation type and ground sightings. Then, areas where sheep were not found or reintroduced were eliminated.
